Ingredients You’ll Need

2 red onions: Choose firm onions for the best flavor and texture. If red onions are unavailable, white or yellow onions can be used as a substitute, though the color and sweetness will vary.
1 cup white vinegar: Using white vinegar provides the clean, bright acidity that balances the sweetness of the sugar. Apple cider vinegar is another tasty alternative.
2 tablespoons white sugar: Granulated sugar is best for sweetness. You can substitute with honey or agave syrup for a different flavor, but this will alter the final taste slightly.
2 teaspoons salt: Regular granulated salt works well here to enhance the overall flavor. Sea salt can also be used if preferred.

How to Make Pickled Red Onions

Prepare the Onions: Begin by peeling the 2 red onions and slicing them thinly. A mandoline slicer can ensure that your slices are uniform, but a sharp knife will do just fine as well! Aim for slices about 1/8 inch thick for optimal pickling.
Mix the Brine: In a jug, combine 1 cup white vinegar, 2 tablespoons white sugar, and 2 teaspoons salt. Stir these ingredients until the sugar and salt dissolve completely into the vinegar.
Blanch the Onions: Place the sliced onions in a heatproof bowl and pour over boiling water, allowing them to sit for 30 to 60 seconds. This step softens the onions and helps them absorb the brine better. After that, drain the onions well.
Pack the Jars: Next, pack the drained onion slices into clean jars, making sure to leave a little space at the top. Pour the brine mixture over the onions, pressing them down gently so they are fully submerged.
Cool and Refrigerate: Allow the jars to cool to room temperature. Seal them tightly and store them in the refrigerator. Your pickled onions will be ready to enjoy in about 30 minutes and can last for 2 to 3 weeks in the fridge.

Storing & Reheating

These pickled red onions can be stored in the refrigerator for up to 2–3 weeks when kept in an airtight container. They should not be kept at room temperature for long due to the high vinegar content. While freezing is not recommended—since it alters the crispy texture—you can keep them in the fridge and directly consume them as needed. They’re best served cold, enhancing flavor and crunch without additional heating.

Chef’s Helpful Tips

Slice Evenly: Ensuring uniform thickness in your onion slices helps them pickle evenly. So, take your time with this step.
Brine Variations: Feel free to experiment with spices in your brine, like adding black peppercorns, garlic, or red pepper flakes for extra flavor.
Check the Taste: After 30 minutes of resting, whisk the onions and try a slice. If you want more flavor, let them sit longer in the brine.
Make-Ahead: For best results, prepare these pickled onions a day ahead of your event to let the flavors deepen.
Use a Jar Funnel: If pouring the brine into small jars becomes messy, a jar funnel simplifies the process and minimize spills.

There’s something truly special about homemade pickled red onions. Not only do they add a pop of color and crunch to your meals, but they also offer a satisfying tangy-sweet flavor that perfectly complements many dishes. Infusing your meals with a little zing can turn the simplest of dinners into culinary highlights. You’ll find they elevate everything from everyday sandwiches to elaborate holiday spreads.
